Rim martini glasses with sugar crystals. A quick and easy way is to dip a clean finger into a cup of water, shake off the excess, and run your fingertip around the rim. Then immediately dip the rim in a small plate of sugar.

In a blender, combine eggnog, brandy, almond liqueur, ice cream, and nutmeg until smooth. I highly recommend that you place the brandy and almond liqueur in the refrigerator to chill the day before making these cocktails (or place in freezer for an hour or two). This will ensure a very nicely chilled drink. If you like your drinks even colder, and like some ice bits, blitz some chopped ice along with all the ingredients. Placing your glasses in the refrigerator or freezer a couple hours before serving also gives these drinks a frosty edge.

Pour into sugar rimmed glasses. Garnish with a sprinkling of cinnamon and serve immediately.

To make this recipe a few hours ahead of time, simply blend the cocktail ingredients together and then place the blender carafe in the refrigerator. Give it a good stir to incorporate all the ingredients before pouring it into sugar rimmed glasses and garnishing with cinnamon.
